Attention: Chief, Compilance Unit 230 South Dearborn Street Chicago, Illinois 60604

Subject:

NPDES Non-Compliances for Quad-Cities Generating Station IL-0005037

Dear Sirs:

In accordance with Standard Condition 12 we wish to submit the following notice of non-compliances:

DISCHARGE: 005 Sanitary Treatment Plant PARAMETER AND PERMIT LIMIT: Fecal Co11 form 400 colonies / 100 ml NON-COMPLIANCE AND DATE: Fecal Coliform > 400 colonies / 100 ml on January 28, 1987 Too Numerous To Count (T.N.T.C.)

CAUSE: The chlorinator tablet tubes have spacers in the bottom of them to control Cl concentration. Very low flow caused the effluent not to come in contact with the tablets. A concentration was 0.4 ppm on the day of the non-compliance.

CORRECTIVE ACTION: Removed spacers from both tablet tubes to allow for low flows, no pumps on, to come in contact with tablets to maintain adequate Cl residual.

If there are any questions, please call Ray Moore of my staff at 309-654-2241, Extension 2731.
